Magnetostatic waves (MSWs) in magnetodielectric media are fundamental for the creation of various highly efficient devices for analog information processing in the microwave range. These devices include various filters, delay lines, phase shifters, frequency converters, nonreciprocal and nonlinear devices, and others.

Magnetostatic Waves in Inhomogeneous Fields examines magnetostatic waves and their distribution in non-uniformly magnetized films and structures. The propagation of magnetostatic waves in magnetodielectric environments is accompanied by numerous and very diverse physical effects, sharply distinguishing them from ordinary electromagnetic waves in isotropic media. The authors address dispersion properties and noncollinearity of phase and group velocity vectors, as well as non-reciprocal propagation.
